Introduction

Bindings to the libssh2 library which provide access to resources (shell, remote exec, tunneling, file transfer) on a remote machine using a secure cryptographic transport.

Installation

Windows binaries may be found at http://snaps.php.net/. To install, download php_ssh2.dll to the folder specified by your php.ini file's extension_dir directive. Enable it by adding extension=php_ssh2.dll to your php.ini and restarting your webserver.

extension_dir=c:/php5/exts/
extension=php_ssh2.dll

Linux, BSD, and other *nix variants can be compiled using the following steps:

• Download and install OpenSSL. If you install OpenSSL via your distribution's packaging system be sure to install the development libraries as well. This will typically be a package named openssl-dev, openssl_devel, or some variation thereof.

• Download and install libssh2. Typically this means executing the following command from the libssh2 source tree. ./configure && make all install.

• Run the pear installer for PECL/ssh2: pear install ssh2

• Copy ssh2.so from the directory indicated by the build process to the location specified in your php.ini file under extension_dir.

• Add extension=ssh2.so to your php.ini

• Restart your webserver to reload your php.ini settings.
